Mending plates are obtainable in many shapes and sizes. They are made of steel with holes counter
sunk, so that when a flathead screw is used, the head will be flush with the surface of the plate. These plates are ideal for reinforcing almost any kind of wood joint. They are especially good for screen-frame repair work. Mending plates should always be attached with wood screws, never nails.
BOLTS
The advantage of using a nut and bolt to make a wool joint, rather than a nail or wood screw, is that the joint can be taken apart easily and as often as necessary without damage to the wood. The sections of
any portable structure should be bolted rather than screwed or nailed together. On many heavy woodworking jobs the home mechanic will find that bolts are easier to install and give better results than wood screws or nails. Drill a hole first which corresponds to the size of the bolt to be used. Place a washer over the end of the bolt and run down the nut. The washer will prevent the nut from coming loose and keep the wood from being damaged as the nut is tightened. Turning in the bolt too much will damage the threads.
Machine bolts have a square head that can be held with a wrcnch. Carriage bolts have an oval head,
but the shank is square for a short distance below the head, preventing the head from turning in the wood as the nut is tightened. Use a monkey wrench or a spanner to tighten.
ABRASIVES
Sandpaper. The term sandpaper is used throughout this book to describe the type of abrasive paper commonly used for smoothing down a wood surface. Actually, no abrasive paper is made out of sand because it is not very effective. 'l'he very coarse grades of abrasive paper are made with flint, while the finer grades are made out of garnet.
There are two systems for grading abrasive papers, but the one most commonly used starts at 3%. This is very coarse paper, good for little except very rough work. The scale runs to 9/0, which is very fine. In between are the medium papers, such as Nos. 1, 112, 0, 00, and these are suitable for most jobs in the home workshop.
Steel Wool. Steel wool is an excellent abrasive for the workshop because it is pliable and can be worked around curves in furniture and in other places difficult to work with sandpaper. Steel wool is also less likely to scratch a finish and may, therefore, be used on enamel. Steel wool is graded by the same system used for sandpaper, but it is somewhat finer throughout.
Very fine abrasives, such as pumice stone, are used for polishing.
Sanding shouid always be done with the wood grain, to avoid damaging the wood. You will find that in most cases you can begin with one of the rather coarse grades and work down to the finer grades as the wood surface becomes smoother.
After the sanding has been completed, the wood should be dusted carefully. This is very important if the surface is to be varnished.
